The 'Kühlstein Wagenbau' of
Berlin-Charlottenburg produced
electric cars from 1898 to 1902. Some were vehicles of in-house design, others were
Jeantaud cabs built under licence. The firm also built tractor units to replace horses for use with
horse-drawn carriages. Later models were also known as Kühlstein-Vollmer. Production of these vehicles was absorbed by
AEG in 1902 or 1903.
